  • Under the hood

    We are proud of how our services look on the outside, but we've also made sure it runs like clockwork on the inside.

    Powerful API

    You can make C42 do pretty much anything with the C42 API. Except for showing up, that’s something you still need to do yourself!


    To get started check our API & Application Frameworks documentation.

    Enterprise integration

    C42 can and will integrate with your standard calendar solutions. On top of that we offer integrations with Exchange, HRM, ERP and legacy systems.


    We have powerful APIs and connectors that will make syncing with your system easy and straightforward.

    Web integrations

    (coming soon!)

    Zapier makes it easy to sync data between your web apps (>250 web services!), so you don’t need to be a developer to make C42 notifications trigger other software, or use your other web solutions to enrich your C42 experience!

    Controlled hosting

    Hosted on highly trusted environments. Al our services are

    • ISP & data centre independent.
    • geographically spread &
    • hosted in the Netherlands.

    Backups & SLA

    Information you provide to work efficiently with our platform, is stored on secure servers and securely backed up on a minimum of two different locations for added security. We have a 99.5% guaranteed uptime and a dedicated team standing by to make sure that we live up to our SLA promises.

    Safe & Secure

    We take the matter of security very seriously and do our utmost to protect your data with state of the art security standards and protocols. Transaction of data is encrypted (AES) for your safety. The password you use for your personal authorization is hashed (salted PBKDF2) and we use token verification for authentication.
